My First Scene in After Effects!

I took my first scene into After Effect to try and make the scene look night from the shot that i shot in the day. This is the before picture.

This is what it looks like after.

I did this by adding gradients to the top and bottom of the image and then using a blue colour tint with a stepped up exposure to bring out the whites of the image. I think this has worked well and i think it looks like a night time shot.
